WARNING: You are viewing an old version of the VIC documentation. Please visit http://vic.readthedocs.org for the most current documentation.


Note: The VIC model and the routing model have been developed for use on LINUX and UNIX platforms. To use VIC and/or the routing model on a Windows platform, we suggest downloading a free UNIX emulator such as Cygwin and compiling/running these models within this emulator. Please do not ask us for help with installing or using Cygwin.

VIC Model Source Code

The VIC model is written in C and typically compiled with the GNU gcc compiler.

Access: The VIC model source code is archived in Git and is publicly available through GitHub. To access the source code, visit GitHub, create an account, and visit github.com/UW-Hydro/VIC.

Routing Model Source Code

The routing model is written in Fortran 77 and typically compiled with the GNU g77 compiler (not to be confused with GNU's gfortran compiler, which may also work but hasn't been tested here in our lab).

Sample Data Sets

Input Parameter Files and Meteorological Forcings

We have already created input parameters and forcing files for the entire globe (0.5 degree) and the continental US (1/8 degree). Save yourself some trouble and use these inputs. We only ask that you cite the relevant papers associated with the datasets.

NOTE: we do not guarantee that the soil parameters are optimal for the basin(s) you wish to simulate. We recommend that you calibrate (b_infilt, baseflow parameters Ds, Ws, Dsmax (ARNO formulation) or d1-d3 (NIJSSEN2001 formulation), and soil layer thicknesses). See below for information about calibration.
